Rainier became the Sovereign Prince of Monaco at the age of 25 upon the death of his maternal grandfather, Prince Louis II, on 9 May 1949.
Reign

After ascending the throne, Rainier III worked to recoup Monaco's lustre, which had become tarnished through financial neglect and scandal (his mother, Princess Charlotte, took a noted jewel thief known as René the Cane as her lover). Upon ascension, the Prince found a treasury that was practically empty. Monaco's traditional gambling clientele, largely European aristocrats, found themselves with reduced funds after World War II. Other successful gambling centres had opened to compete with Monaco. To compensate for the loss of income, Rainier decided to promote Monaco as a

, who took control of the
Société des Bains de Mer and envisioned Monaco as solely a gambling resort. Prince Rainier regained control of SBM in 1964, effectively ensuring that his vision of Monaco would be implemented.
During his reign, the
Societé Monégasque de Banques et de Métaux Précieux, a bank which held a significant amount of Monaco's capital, was bankrupted by its investments in a media company in 1955, leading to the resignation of Monaco's cabinet. In 1962, Rainier ratified the Principality's new constitution, which significantly reduced the power of the sovereign. He had suspended the previous constitution in 1959, saying that it "has hindered the administrative and political life of the country". The changes ended autocratic rule, placing power with both the Prince and a National Council of eighteen elected members.

Personal life
In the 1940s and 1950s, Rainier had a ten-year relationship with the French film actress
Gisèle Pascal, whom he had met while a student at Montpellier University,
and the couple lived at Saint-Jean-Cap-Ferrat. Rainier's sister,
Princess Antoinette, wishing her own son to ascend the throne, spread rumors that Pascal was infertile. The rumours combined with a snobbery over Pascal's family origins ultimately ended the relationship.
Rainier established a postal museum in 1950: the
Museum of Stamps and Coins, in Monaco's
Fontvieille district
by using the collections of the Monegasque princes
Albert I and
Louis II. The prestigious philatelic collectors organization, Club de Monte-Carlo de l'Élite de la Philatélie, was established in 1999 under his direct patronage. The club is headquartered at the postal museum, and its membership restricted to institutions and one hundred prestigious collectors.
Rainier organized exhibitions of rare and exceptional postage stamps and letters with the club's members.
